To all whom it natty concern:

Be it known that I, WiLLIAM HENRY MORGAN, of Alliance, in the county of Stark and State of Ohio, have'invented certain new and useful Improvements in Overhead Traveling Cranes; and I do herebyde'clare the following to be a-full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in overhead traveling cranes; and it consists, broadly, in a main crane carrying a trolley and an auxiliary crane carried by the main crane and located in a plane above the main trolley. p

This invention further consists in a main traveling bridge carrying a traveling trolley, a supplemental traveling bridge carried on the main bridge, and an auxiliary trolley mounted to. travel on the supplemental bridge.

My invention further consists in the parts and combinations of parts, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in end elevation of my improved double crane. Fig. 2 is a view in side elevation, showing the double bridges with a trolley on each. Figs. 3 and 4 are similar views of modifications. Fig. 5 is a view in end elevation of another modified form, and Figs. 6 and 7 are views of another modification.

1 represents the end carriages of an overhead traveling crane, mounted on trucks 2, the wheels 3 of which travel on elevated tracks 4. These end carriages 1 are connected by the main-bridge girders 5, having rails 6, on which the main hoist trolley 7 travels. This main trolley travels lengthwise the girders 5 and carries the main hoist drum or drums 8 and is also provided with a motor or motors and gearing for actuating the drum and with a motor and gearing for the cross-travel of the trolley.

The bridge or crane comprising the end carriages 1, girders 5, and trucks 2 is propelled on its trackway 4 by motor and gearing in the well known and ordinary manner.

Secured to the end carriages 1, near the ends of the latter, are the upright posts 9, two to each carriage. The posts of each end carriage are preferably connected near their tops, and the four posts thus located and arranged carry and support the top girders 10, which constitute the trackway for the auxiliary bridge 11.. These girders 10 are parallel with the main girders 5, but are in vertical planes outside the main girders, and the auxiliary traveling bridge 11, mounted on these girders, is located at right angles to the main girders 5, thus permitting the trolley 12 on the auxiliary bridge 11 to move in a direction at right angles to the length of the 6 main girders 5, so that the hoist-chain 13 for the auxiliary trolley may be 10 wered between the main girders 5 or to either side of said main girders.

The auxiliary bridge 11 consists of end carriages 14, having wheels 15, mounted on rails carried by the top girders 10 and bridgegirders 16, secured to said end carriages 14 and provided on their upper surfaces with rails, 17, on which the trolley 12 travels.

With this apparatus the main trolley 7 is designed for heavy work, while the auxiliary trolley 12 may be employed for tilting ladies carried by the main trolley, for lifting light objects, for assisting the main trolley, and also for handling parts of the main trolley or bridge in assembling or while repairing the main crane.

In Figs. 3 and 4 the construction is identical with that disclosed in Figs. 1 and 2, ex- 8 5 cept that the traveling trolley on the upper auxiliary bridge is dispensed with. In the construction shown in the modification the hoisting mechanism 12" of the auxiliary bridge 11 is fixed to the latter, so that the hoist-chain 13, depends centrally between the girders of the main bridge.

Instead of constructing the upper crane 11 to travel as shown in Figs. 1 to 4, inclusive, the girders 16 thereof may be fixed to the 5 top girders 10, as shown in Fig. 5. In this construction the hoisting mechanism may be on a trolley, as shown in Figs. 1. and 2, or it may be fixed, as shown in Figs. 3 and 4.

In the construction shown in Figs. 6 and 7 the two upright posts 9 at the end of each end carriage are connected by girders 16", the

latter being rigidly secured to the upper ends of the upright posts. These girders 16 project beyond the end carriages 1 of the main crane, as clearly shown in Fig. 6, and each girder 16 is provided on its upper surface with a rail 17, the two rails 17 at the opposite end of the bridge constituting a trackway on which an upper or auxiliary bridge travels. This bridge travels on the girders 16 in the direction of travel of the main bridge and,like the main bridge, is composed of two end carriages 18 and two parallel girders 19, the latter being parallel with the girders of the main crane. The girders 19 are provided on their upper surfaces with the rails 20, on which the trolley 21 travels. This trolley has a hoisting-drum and a motor and gearing for actuating the latter and motor and gearing for propelling the trolley on its trackway. With this construction the upper bridge can be moved laterally, so as to bring the hoist-chain of the auxiliary trolley 21 between or to either side of the mainbridge girders, and by moving the trolley 21 on its girders 19 the trolley can be moved to bring its hoist-chains at either end of the main trolley.

It is evident that many slight changes might be made in the relative arrangement of parts shown and described without de parting from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction of parts shown and described; but,
